This is an educational talk about flies

Ichneumon flies, deadly killers
Collectively catching caterpillars
Hatching their eggs in the wounds of the wounded
Beg, beat or steal from whomever he chooses

Wo-oh 

Worker wasp familiar infact
Three sided needle illiterate cats
Sharp-toothed mandibles that work in the grooves
Insects protect and don't often like to loose

Wo-oh
